ABSTRACT

Compositions for oxidation dyeing of keratin fibers, in particular human keratin fibers such as hair, comprising, in a dyeing medium, at least one oxidation dye, at least one thickening polymer comprising at least one fatty chain and at least one fatty alcohol chosen from monoglycerolated and polyglycerolated fatty alcohols. Processes comprising such oxidation dyeing compositions.

[0001] The present invention relates to cosmetic compositions foroxidation dyeing of keratin fibers, such as human keratin fibers likehair, comprising, in a dyeing medium, (1) at least one oxidation dye,(2) at least one thickening polymer comprising at least one fatty chain,and (3) at least one fatty alcohol chosen from monoglycerolated andpolyglycerolated fatty alcohols.

[0002] It is known to dye keratin fibers, for example human hair, withdyeing compositions comprising oxidation dye precursors, generallycalled “oxidation bases.” Representative oxidation bases include ortho-and para-phenylenediamines, ortho- and para-aminophenols, andheterocyclic bases.

[0003] Oxidation dye precursors are compounds initially only slightlycolored or not colored that develop their dyeing power in the hair inthe presence of oxidizing agents, leading to the formation of coloredcompounds. The formation of these colored compounds results either fromoxidative condensation of the “oxidation bases” with themselves, oroxidative condensation of the “oxidation bases” with color-modifyingcompounds, or “couplers,” which are generally present in the dyeingcompositions used in oxidation dyeing. Representative couplers includemeta-phenylenediamines, meta-aminophenols, meta-diphenols, and certainheterocyclic compounds.

[0004] The variety of compositions that can be employed in oxidationcoloration, chosen from oxidation bases, oxidation couplers and mixturesof oxidation bases and couplers, can contribute to a pallet very rich incolor.

[0005] Traditional thickeners, which can provide a gelling effect whendiluted by water and/or surfactants, have been used conventionally tolocalize the dye product as applied on hair, so that the dye productdoes not touch the face or the area outside the area to be dyed. Suchthickeners, chosen as appropriate, for example include crosslinkedpolyacrylic acid, hydroxyethylcelluloses, certain polyurethanes, waxesor mixtures of nonionic surfactants having an HLB (HydrophilicLipophilic Balance).

[0006] However, the inventors have observed that the above-mentionedthickening systems may impede a result of intense and chromatic shadesof low selectivity and good fastness and a good cosmetic condition tothe treated hair. However, it has also been observed that theready-to-use dyeing compositions comprising known oxidation dye(s) andthickening systems tend to result in imprecise application of suchcompositions and/or a decrease in viscosity over time.

[0007] The inventors have discovered that it is possible to obtainready-to-use oxidation dyeing compositions that resist running and tendto remain well-confined to the site of application. Additionally, suchcompositions may favor more intense and more chromatic (radiant) shades,while exhibiting low selectivities and good fastness toward chemicalagents (shampoo, permanent waving and the like) and/or natural agents(light, perspiration and the like), and while offering the hair goodcosmetic properties. The inventors have discovered that it is possibleto obtain at least one of the aforementioned characteristics byformulating a ready-to-use cosmetic dyeing composition comprising (1) atleast one oxidation dye, (2) at least one thickening polymer comprisingat least one fatty chain, and (3) at least one fatty alcohol chosen frommonoglycerolated and polyglycerolated fatty alcohols.

[0008] The inventors have discovered that it is possible to obtain atleast one of the aforementioned characteristics by formulating aready-to-use cosmetic dyeing composition comprising (1) at least oneoxidation dye, (2) at least one thickening polymer comprising at leastone fatty chain, and (3) at least one fatty alcohol chosen frommonoglycerolated and polyglycerolated fatty alcohols.

[0009] The inventors have also discovered that said compositionscomprising (1) at least one oxidation dye, (2) at least one thickeningpolymer comprising at least one fatty chain, and (3) at least one fattyalcohol chosen from monoglycerolated and polyglycerolated fatty alcoholstend to be stable upon storage.

[0010] At least one of these discoveries forms the basis of the presentinvention.

[0012] Another subject of the invention relates to a ready-to-usecosmetic composition for oxidation dyeing keratin fibers comprising, ina dyeing medium, (1) at least one oxidation dye, (2) at least onethickening polymer comprising at least one fatty chain, (3) at least onefatty alcohol chosen from monoglycerolated and polyglycerolated fattyalcohols, and (4) at least one oxidizing agent. The term “ready-to-usecomposition” is understood to mean, for the purposes of the presentinvention, a composition intended to be applied immediately to thekeratin fibers, either stored as it is before use or obtained from themixture of two or more compositions.

[0013] The invention also relates to a method for oxidation dyeingkeratin fibers, such as human keratin fibers like hair, comprisingapplying to said keratin fibers at least one composition (A) comprising,in a dyeing medium:

[0017] A variation of the above-described method is a method foroxidation dyeing keratin fibers, such as human keratin fibers like hair,comprising:

[0018] applying to said keratin fibers at least one dyeing compositioncomprising, in a dyeing medium, at least one oxidation dye and at leastone fatty alcohol chosen from monoglycerolated and polyglycerolatedfatty alcohols, and optionally comprising at least one thickeningpolymer comprising at least one fatty chain,

[0019] developing the color with the aid of at least one oxidizingcomposition comprising at least one oxidizing agent and an effectivequantity of at least one thickening polymer comprising at least onefatty chain,

[0020] wherein said at least one oxidizing composition is combined atthe time of use with said at least one dyeing composition or whereinsaid at least one oxidizing composition is applied sequentially to saidat least one dyeing composition without intermediate rinsing.
